Much of the Treme neighborhood fell dark Monday night, as a power outage affecting nearly 2,200 customers struck at 11:13 p.m.

Entergy New Orleans offered no immediate explanation for the outage, but said service crews were working to restore electric power as quickly as possible.

The initial estimate on the repair said service should be restored by approximately 2 a.m. Tuesday.

Entergy's service map showed the outage contained mainly in a grid from St. Bernard Avenue to Orleans Avenue, and from North Rampart Street to North Galvez Street. Single streets with outages stretched as far as Poydras Street and to a portion of Frenchmen Street in Faubourg Marigny.
